Description

Technical Field

[0001] This invention relates to the field of foam brick molding technology, specifically to a foam brick molding machine and molding process. Background Technology

[0002] Foam bricks, with their advantages of being lightweight, heat-insulating, sound-insulating, and environmentally friendly, are widely used in building walls, partitions, and insulation projects, and are currently one of the mainstream products in new wall materials. As the core equipment of the production line, the foam brick molding machine's molding efficiency, degree of automation, and product stability directly determine the production line's capacity and production costs.

[0003] Currently, traditional foam brick molding equipment generally employs a method of separate pallet conveying, manual placement of foam cores, and mold pressing during molding. The specific process is as follows: first, a pallet conveying mechanism delivers the pallet to the workstation below the mold; the operator manually places the foam cores on the pallet; after the foam cores are in place, the mold descends, pressing the foam cores into the mold cavity to complete the brick molding. This method relies on manual labor to load, position, and place the foam cores at the molding station, representing a semi-mechanized, semi-manual operation mode.

[0004] Therefore, existing foam brick molding machines and processes, due to their high degree of manual intervention, poor process coordination, and low level of automation, can no longer meet the demands for efficient, stable, safe, and low-cost large-scale production. Thus, developing a foam brick molding machine and process capable of automatically and synchronously conveying, positioning, and pressing the pallet and foam core has become an urgent technical problem to be solved in this field.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Summary of the Invention

[0009] The pallet conveying mechanism includes a translation frame assembly and a pallet feeding cylinder. The pallet feeding cylinder is mounted on the frame, and its piston rod is connected to the translation frame assembly. The translation frame assembly is equipped with a baffle plate. The foam board conveying mechanism includes a foam board traveling frame and a traveling frame transmission assembly. The foam board traveling frame includes a foam base plate, and front and rear side plates are provided on the front and rear sides of the foam base plate. Rollers are rotatably connected on the front and rear side plates. A first guide rail is provided on the frame, and the rollers roll in cooperation with the first guide rail. The traveling frame transmission assembly drives the foam board traveling frame to move horizontally.

[0010] Furthermore, the translation frame assembly includes a translation frame body, a traveling shaft, and guide wheels. The traveling shaft is rotatably connected to the inlet and outlet ends of the translation frame body. The guide wheels are sleeved on both ends of the traveling shaft. A guide plate is provided on the frame, and a guide groove is provided on the side wall of the guide plate. The guide wheels roll in cooperation with the guide groove. A baffle shaft is provided on the side wall of the translation frame body, and a baffle plate is connected to the baffle shaft.

[0011] Furthermore, the walking frame transmission assembly includes a first motor, a drive chain, a drive shaft, and a driven shaft. The first motor is connected to the frame, the drive shaft is rotatably connected to the exit plate end of the frame, and the driven shaft is rotatably connected to the inlet plate end of the frame. The output shaft of the first motor is provided with a drive wheel, and the drive shaft is fitted with a driven wheel. The drive wheel and the driven wheel are driven by a chain.

[0012] Furthermore, the inlet end of the frame is equipped with a bamboo board box, and there is an outlet gap between the lower end of the bamboo board box and the frame.

[0013] A molding process for a foam brick molding machine includes the following steps:

[0014] S1: Material preparation: Arrange the foam core neatly on the foam base plate of the foam board conveying mechanism, and at the same time stack the pallets in the bamboo box at the board inlet end of the frame to complete the material preparation before production;

[0015] S2: Foam board conveying: Start the walking frame transmission assembly. The first motor drives the foam board walking frame to move forward along the frame guide rail through the chain and transmission shaft, and smoothly delivers the foam base plate carrying the foam core to the molding station directly below the molding mold.

[0016] S3: Pallet conveying: The pallet feeding cylinder drives the translation frame assembly to move forward. The baffle plate on the translation frame pushes the pallet in the bamboo board box out of the board discharge gap. The pallet is conveyed to the corresponding position below the foam board walking frame and directly below the forming mold, realizing the double-layer positioning of the pallet and the foam board.

[0017] S4: Mold Pre-pressing and Positioning: The hydraulic press drives the molding mold downwards. The upper pressure head cooperates with the lower mold frame to initially press the foam core on the foam base plate into the molding cavity. The guide ribs and guide rods simultaneously complete the guiding and positioning of the foam core. The first positioning groove and the second positioning block cooperate with each other, and the first positioning block and the second positioning groove cooperate with each other to ensure accurate pressing position.

[0018] S5: Foam board exit and reset: After the foam core is clamped and fixed by the mold, the walking frame transmission component rotates in reverse, driving the foam board walking frame and foam base plate to move backward, exit the molding station and reset to the initial position;

[0019] S6: Compression molding: The hydraulic press continues to drive the molding die downward, moving the die to the pallet. The material feeder sends the material into the molding cavity. The upper pressure head descends to apply pressure to the material in the molding cavity. The mold core and the molding cavity cooperate to complete the compression and molding of the foam brick.

[0020] S7: Demolding and unloading: After the pressure holding and shaping are completed, the hydraulic press drives the molding mold to move upward and reset. The molded foam bricks remain on the pallet. The pallet conveying mechanism sends the pallet carrying the finished product out of the molding station to complete one molding cycle. Then, the above steps are repeated to realize the continuous automated production of foam bricks.

[0021] This invention provides a foam brick molding machine and molding process. It has the following beneficial effects:

[0022] 1. This invention, through the integrated design of the feeding device and the molding device, completely replaces the traditional manual placement of foam cores, achieving full automation of the entire process from pallet conveying, foam core conveying, mold positioning, pressing and molding, to demolding and unloading. This fundamentally solves the problems of low efficiency and high reliance on manual labor in existing technologies. The equipment adopts a double-layer synchronous conveying structure, allowing the foam board and pallet to be conveyed independently and precisely positioned in both layers. The foam cores are pre-arranged uniformly on the foam base plate and automatically delivered to the workstation by the machine, eliminating the need for repeated manual placement under the mold. This significantly shortens process connection time, substantially improves production cycle and overall capacity, and reduces labor intensity and costs.

[0023] 2. This invention ensures molding accuracy through a multi-guided positioning structure in the mold. Guide ribs, guide rods, positioning grooves, and positioning blocks are installed within the molding cavity, enabling precise guidance and positioning of the foam core as it enters the mold cavity. The upper pressure head and lower mold frame are interlocked and pressed together by the positioning structure, effectively preventing problems such as foam core misalignment, skewing, and omission, significantly reducing the scrap rate and improving the dimensional accuracy and quality stability of the finished foam bricks. Simultaneously, the fully automated mechanical operation eliminates the need for operators to have close contact with the mold, removing safety hazards such as hand compression and collisions, and significantly improving production safety and equipment reliability.

[0024] 3. The molding process of this invention is smooth and continuous, with each step—feeding, pre-pressing, unloading, material distribution, pressing, and demolding—working in an orderly and coordinated manner. The equipment has a reasonable structural layout and stable operation, and can be directly adapted to existing foam brick production lines, resulting in low modification and usage costs. The entire set of equipment is highly automated and easy to operate, enabling continuous and large-scale production. It fully meets the demands of modern building materials production for high efficiency, stability, safety, and low cost, effectively improving the overall intelligence level and economic benefits of the production line.

Detailed Implementation

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see the appendix Figure 1 -Appendix Figure 13This invention provides a foam brick forming machine, including a feeding device and a forming device. The feeding device includes a frame, a pallet conveying mechanism and a foam board conveying mechanism mounted on the frame. The forming device includes a hydraulic press and a forming mold. The hydraulic press is connected to the outlet end of the feeding device, and the forming mold is connected to the power output end of the hydraulic press. A bamboo board box 51 is provided at the inlet end of the frame. The lower end of the bamboo board box 51 is fixedly connected to the frame, and there is an outlet gap between the lower part of the bamboo board box 51 and the frame. The forming mold includes a lower mold frame 1 and an upper pressure head 2. Several forming cavities 11 are arranged in a matrix below the lower mold frame 1. An upper sealing plate 3 is provided at the upper end of the forming cavity 11. Vertically extending guide ribs 41 are provided on the front and rear sidewalls of the forming cavity 11 below the upper sealing plate 3. The cross-section of the guide ribs 41 is triangular. The guide ribs 41 mainly cooperate with the front and rear sidewalls of the foam board, so that when the lower mold frame 1 descends, the foam board can be smoothly guided into the forming cavity 11 by the guide ribs 41, while also restricting the movement of the foam board. The upper sealing plate 3 is provided with a guide rod 42 that extends into the molding cavity 11. The guide rod 42 can cooperate with the holes on the foam board to play a positioning role, so that the foam board and the lower mold frame 1 can be more accurately matched. The outer structure of the upper sealing plate 3 is the same as that of the foam board. Therefore, the left side wall and the right side wall of the upper sealing plate 3 are provided with first positioning grooves 31 and first positioning blocks 32 that are spaced apart. The first positioning grooves 31 on the left side wall of the upper sealing plate 3 correspond one-to-one with the first positioning blocks 32 on the right side wall of the upper sealing plate 3, and the first positioning blocks 32 on the left side wall of the upper sealing plate 3 also correspond one-to-one with the first positioning grooves 31 on the right side wall of the upper sealing plate 3. Both the first positioning grooves 31 and the first positioning blocks 32 are trapezoidal.

[0041] In this embodiment, the upper end of the guide rod 42 is embedded in the upper sealing plate 3. Two guide rods 42 are provided, symmetrically arranged front and rear. The lower end of the guide rod 42 is provided with a guide cone surface 421. The guide cone surface 421 allows the guide rod 42 to better extend into the holes of the foam board, achieving a precise guiding and positioning effect. Through the dual cooperation of the guide rod 42 and the guide rib 41, the fitting accuracy between the foam board and the molding cavity 11 can be effectively improved.

[0042] In this embodiment, the upper end of the molding cavity 11 is also provided with a connecting rod 43, which is symmetrically arranged on the left and right sides of the upper sealing plate 3. The lower end of the connecting rod 43 is provided with several mold cores 44. The mold cores 44 enable the foam brick after pressing to have a molding groove. In addition, the lower mold frame 1 is provided with connecting ears 12 on both sides. The connecting ears 12 are mainly connected to the lifting cylinder, and the lower mold frame 1 is driven to move up and down by the lifting cylinder.

[0043] In this embodiment, the upper pressure head 2 includes an upper template 21. The lower end of the upper template 21 is provided with a first support plate 22 and a second support plate 23. The first support plate 22 and the second support plate 23 are symmetrically arranged in the molding cavity 11. The first support plate 22 extends between the upper sealing plate 3 and the connecting rod 43, and the second support plate 23 extends between the connecting rod 43 and the side wall of the molding cavity 11.

[0044] In this embodiment, a first pressure plate 24 is provided at the lower end of the first support plate 22, and a second pressure plate 25 is provided at the lower end of the second support plate 23. The inner sidewall of the first pressure plate 24 is provided with spaced-apart second positioning blocks 26 and second positioning grooves 27. When the upper pressure head 2 presses down, the second positioning blocks 26 can engage with the first positioning grooves 31, and the second positioning grooves 27 can engage with the first positioning blocks 32. This allows the first pressure plate 24 to pass through the upper sealing plate 3 and enter the molding cavity 11. Furthermore, the sidewalls of the first support plate 22 and the second support plate 23 are provided with through holes 28. A limiting post 29 is provided at the lower end of the upper template 21, which serves to limit the movement of the upper template 21 as it descends.

[0045] In this embodiment, the pallet conveying mechanism includes a translation frame assembly and a pallet feeding cylinder 61. The translation frame assembly is slidably connected to the frame 5, and the pallet feeding cylinder 61 is mounted on the frame 5. The piston rod of the pallet feeding cylinder 61 is connected to the translation frame assembly, and the translation frame assembly is provided with a baffle plate 66. The pallet feeding cylinder 61 can drive the translation frame assembly forward or backward. When the translation frame assembly moves forward, the baffle plate 66 can push the pallet in the bamboo box 51 out through the pallet outlet gap, thereby playing the role of conveying the pallet. Specifically, the translation frame assembly includes a translation frame body 62, a traveling shaft 63, and guide wheels 64. The traveling shaft 63 is rotatably connected to the inlet end and the outlet end of the translation frame body 62, and the guide wheels 64 are sleeved on both ends of the traveling shaft 63. The frame 5 is provided with a guide plate 53, and the side wall of the guide plate 53 is provided with a guide groove 54. The guide wheels 64 are in rolling cooperation with the guide groove. The piston rod of the pallet feeding cylinder 61 is connected to the translation frame body 62. The side wall of the translation frame 62 is provided with a baffle shaft 65, and a baffle plate 66 is connected to the baffle shaft 65.

In this way, when the translation frame 62 is reset, the baffle plate 66 can rotate to make room, and then reset under the action of the torsion spring.

[0046] In this embodiment, the foam board conveying mechanism includes a foam board traveling frame 7 and a traveling frame transmission assembly. The foam board traveling frame 7 is located above the translation frame assembly, and its lower end is slidably connected to the frame 5.

The frame 5 is symmetrically provided with first guide rails 52, and the rollers 74 are in rolling cooperation with the first guide rails 52. The walking frame transmission assembly includes a first motor 81, a drive chain 82, a drive shaft 83, and a driven shaft 84. The first motor 81 is connected to the frame 5. The drive shaft 83 is rotatably connected to the outlet end of the frame 5, and the driven shaft 84 is rotatably connected to the inlet end of the frame 5. A drive wheel 811 is mounted on the output shaft of the first motor 81, and a driven wheel 831 is mounted on the drive shaft 83. The drive wheel 811 and the driven wheel 831 are driven by a chain. First transmission wheels 832 are mounted on both ends of the drive shaft 83, and second transmission wheels 841 are mounted on both ends of the driven shaft 84. The drive chain 82 is wound around the first transmission wheels 832 and the second transmission wheels 841, and both ends of the drive chain 82 are connected to the rear side plate 73. With the above structure, the first motor 81 drives the drive shaft 83 to rotate, thereby driving the drive chain 82 to pull the foam board walking frame 7 forward or backward. When the foam board walking frame 7 moves forward, it brings the foam core to the bottom of the press mold.
